Abstract
The utility model provides a check valve without pressure loss, which can automatically control one-way flow for liquid. The utility model comprises an upper body, a valve body, an inflatable ball, a pressing ring, a supporting plate with holes and a lower body, and all the parts are made of anticorrosive material. The liquid flows from top to bottom, and each liquid passage area in the valve is larger than the hole area of an external pipe. When the utility model is applied to the working condition of condensation-recovering, the outlet of a connection pipe at the lower end of the valve is inserted into the liquid below the liquid level. Once the liquid flows back, the liquid level in the pipeline at the lower end of the valve rises, the inflatable ball floats upwards, and the ball being guided by a conical surface inside the upper body blocks a liquid inlet under the action of counter pressure to prevent the backflow. The utility model can also be applied to the closed and circulated pipelines.
